A guide to designing safer polymers based on the principles of green chemistry and the EPA's Polymer Exemption Rule Green chemistry, the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances, is a powerful tool in designing safer polymers. By adhering to the principles of green chemistry, manufacturers can produce polymers that are better for the environment, and can do so in an economically sound manner. The Polymer Exemption Rule delineates types of polymers that are expected to be of reduced risk. By following the guidelines contained within the Polymer Exemption Rule, manufacturers may decrease their regulatory requirements while designing polymers that are environmentally benign. This valuable guide approaches the manufacture of polymers from two perspectives, incorporating the principles of green chemistry with the guidance of the Polymer Exemption Rule to design environmentally benign polymers. Designing Safer Polymers is an indispensable working resource for polymer scientists and engineers, as well as corporate decision makers working in the polymer and chemical industries.

Clearly lays out the issues related to plastics' effects on the environment, while also serving as a practical, non-academic guide for making sustainability decisions about plastics recycling and the newest bio-based plastics Company managers, product developers, policy makers, environmental researchers, and plastics industry engineers are under increasing pressure to find ways of minimizing the environmental footprint of plastic products. This accessible book is designed to help readers understand the life-cycle impacts of various plastics, clarifying the technical research and practical arguments to show when bio-based and recycled plastics might be useful options for reducing the overall energy consumption, greenhouse gas emissions, and waste associated with traditional plastics. Plastics and Sustainability compares traditional fossil fuel-based plastics with bio-based plastics in terms of properties, environmental impacts, and costs -- indicating what the most effective approaches could be for using recycled, biodegradable, or various bio-based materials. The book makes objective comparisons between bioplastics and all commonly used plastics, focusing on how they affect production economics, product requirements, and retailer and consumer needs. It incorporates research concerning life-cycle assessment, production techniques, and commercial applications, and presents "green" guidelines about product design, recycling, processing efficiency, and material selection. The book also reports on recent industry developments and commercial trends in an effort to synthesize conclusions that are necessary for finding the right balance between bio-based and fossil-fuel based plastic products.

Many books focus on individual differences and how those relate to traffic safety such as accident proneness, gender differences, age, alcohol, and the effects of drugs. Others focus on the safety effects regarding the vehicle such as airbags, anti-lock brakes, navigation systems, intelligent cruise control and other new gadgets coming to the vehicle. Even though these topics are undoubtedly important for traffic safety, this book takes a unique approach as it focuses solely on the road environment. Designing Safe Road Systems provides the background for those who want to know more about the effects of road design on driving behaviour. It uses a systems approach to allow a better understanding of why and in what circumstances drivers may commit errors. This understanding will ultimately lead to road systems that prevent (fatal) errors from occurring. The book contains an overview of the current models and theories about human performance and human behaviour in traffic that are relevant for all those involved in designing safe road systems. The central theme of this book is how design principles can reduce the probability of an error while driving. The authors demonstrate how knowledge of human factors helps a road authority to better understand how road users behave. They argue that in many cases the design of the environment can be further adjusted to human capabilities, and that safety should be considered a system property to be built into the road system.

Polymers are an example of “products-by-process”, where the final product properties are mostly determined during manufacture, in the reactor. An understanding of processes occurring in the polymerization reactor is therefore crucial to achieving efficient, consistent, safe and environmentally friendly production of polymeric materials. Polymer Reaction Engineering provides the link between the fundamentals of polymerization kinetics and polymer microstructure achieved in the reactor. Organized according to the type of polymerization, each chapter starts with a description of the main polymers produced by the particular method, their key microstructural features and their applications Polymerization kinetics and its effect on reactor configuration, mass and energy balances and scale-up are covered in detail. The text is illustrated with examples emphasizing general concepts, principles and methodology. Written as an authoritative guide for chemists and chemical engineers in industry and academe, Polymer Reaction Engineering will also be a key reference source for advanced courses in polymer chemistry and technology.

Natural Fiber-Reinforced Biodegradable and Bioresorbable Polymer Composites focuses on key areas of fundamental research and applications of biocomposites. Several key elements that affect the usage of these composites in real-life applications are discussed. There will be a comprehensive review on the different kinds of biocomposites at the beginning of the book, then the different types of natural fibers, bio-polymers, and green nanoparticle biocomposites are discussed as well as their potential for future development and use in engineering biomedical and domestic products. Recently mankind has realized that unless the environment is protected, he himself will be threatened by the over consumption of natural resources as well as a substantial reduction in the amount of fresh air produced in the world. Conservation of forests and the optimal utilization of agricultural and other renewable resources like solar, wind, and tidal energy, have become important topics worldwide. With such concern, the use of renewable resources—such as plant and animal-based, fiber-reinforced polymeric composites—are now becoming an important design criterion for designing and manufacturing components for a broad range of different industrial products. Research on biodegradable polymeric composites can contribute, to some extent, to a much greener and safer environment. For example, in the biomedical and bioengineering fields, the use of natural fiber mixed with biodegradable and bioresorbable polymers can produce joint and bone fixtures to alleviate pain in patients. Includes comprehensive information about the sources, properties, and biodegradability of natural fibers Discusses failure mechanisms and modeling of natural fibers composites Analyzes the effectiveness of using natural materials for enhancing mechanical, thermal, and biodegradable properties
